nature so incurious as mine in _that_ direction, of his interest in the "queer" or the incalculable effects of things. There was apparently for him no possible effect whatever that mightn't be more or less rejoiced in as such--all exclusive of its relation to other things than merely knowing. There recurs to me withal the shamelessness of my own indifference--at which I also, none the less, I think, wondered a little; as if by so much as it hadn't been given me to care for visibly provoked or engineered phenomena, by that same amount was I open to those of the mysteriously or insidiously aggressive, the ambushed or suffered sort. Vivid to me in any case is still the sense of how quite shiningly light, as an activity and an appeal, he had seemed to make everything he gave himself to; so that at first, until the freshness of it failed, he flung this iridescent mantle of interest over the then so grey and scant little scene of the Harvard (the Lawrence) Scientific School, where in the course of the months I had had a glimpse or two of him at work. Early in the autumn of 1861 he went up from Newport to Cambridge to enter that institution; in which thin current rather than in the ostensibly more ample began to flow his long connection with Harvard, gathering in time so many affluents. His letters from Cambridge during the next couple of years, many of them before me now, breathe, I think, all the experience the conditions could have begotten at the best; they mark the beginning of those vivacities and varieties of intellectual and moral reaction which were for the rest of his life to be the more immeasurably candid and vivid, the more numerous above all, and the more interesting and amusing, the closer view one had of him. That of a certainty; yet these familiar pages of youth testify most of all for me perhaps to the forces of amenity and spontaneity, the happy working of all relations, in our family life. In such parts of them as I may cite this will shine sufficiently through--and I shall take for granted thus the interest of small matters that have perhaps but that reflected light to show. It is in a letter to myself, of that September, dated "Drear and Chill Abode," that he appears to have celebrated the first steps of his initiation.
